Asphalt Pavement Alliance's Asphalt Pavement Conference
Innovations in Paving – Pavement Preservation with Plant Mix – Keeping Competitive
This day and a half conference will be broken down into three sessions, Innovations in Paving, Pavement Preservation with Plant Mix, and Keeping Competitive. Using a round table format, contractors and subject matter experts will provide their experiences on each session's theme. Then you will have the chance to break into roundtable discussions to develop questions for the panel. The questions are then consolidated and presented to the panel for their answers. You will not want to miss the informative and interactive conference.
Monday, March 12, 2012
8:00 AM - 10:00 AM
Opening and Session I: Innovations in Paving
Session Moderator: Kent Hansen, P.E., Director of Engineering, National Asphalt Pavement Association
Welcome
Mike Kvach, Executive Director, Asphalt Pavement Alliance
Intelligent Compaction
Bob Horan, P.E., Regional Engineer Asphalt Institute
Bob Horan discusses the latest advancements in Intelligent Compaction technologies, how they work and their practical applications.
The IR Bar (Infrared Bar)
Kyle Swaner, Vice President of Technical Programs, Texas Asphalt Pavement Association
TXDOT, working in partnership with the TXAPA and through the Texas Transportation Institute, put research and technology to work and developed an advanced means of detecting thermal segregation in asphalt pavements. Learn how it works and its impact on further enhancing the quality of asphalt pavements in Texas.
Innovative Paving Project
Reade Dawson, General Manager, S. T. Wooten Corp., North Carolina
The S.T. Wooten Corp. was the winner of the prestigious national Sheldon G. Hayes Award for the 8-mile mill and overlay project on I-795 in Wilson County, NC. Richard Dawson will discuss the unique approach that produced a smoother surface and achieved exceptional pavement quality; they will also share how the company completed its work in just 80 construction days, without accidents and without penalties, while minimizing disruption to the traveling public.
Tire Rubber Modified Asphalt: An Alternative Look
Ted Flanigan, Technical Director, Wright Asphalt Products, LLC
Tire rubber modified asphalt continues to gain acceptance nationwide and the technologies incorporating rubber into asphalt pavements continue to advance. This session will be an overview of these technologies.
10:00 AM - 10:30 AM
Roundtable Discussions
This year's conference is taking a unique approach to answering your questions for the presenters. After hearing the presenters, the participants spend 30 minutes discussing the presentations in a roundtable format and preparing questions for the panel discussion.
10:30 AM - 11:00 AM
10:30 AM - 11:00 AM
Questions/Answers - Panel Discussion
During the break questions prepared during the roundtable discussions are collated. The presenters are brought back to form a panel and answer the questions which are presented by the moderator.
1:00 PM. - 3:00 PM
Session II: Pavement Preservation With Plant-Mix Asphalt
Session Moderator: (TBD)
Thin-lift Asphalt Overlays
Danny Gierhart, P.E., Regional Engineer, Asphalt Institute
Learn about the benefits of using thin-lift asphalt overlays, the conditions in which they are best used and conditions in which an alternative asphalt construction would be better. General materials and construction considerations particular to thin-lift overlays will be discussed.
Ohio Smoothseal
Cliff Ursich, P.E., Executive Director, Ohio Flexible Pavements. and Jim Marszal, P.E., ODOT, Pavement Engineer, ODOT District 12.
Agency and industry partnered on making the thin-lift asphalt product known as Smoothseal successful in solving rehabilitation challenges in Ohio. This session will address Smoothseal's properties, application, and performance characteristics.
North Carolina Model for Thin-Lift Asphalts
Ellis Powell, Director of Technical & Regulatory Services, North Carolina Asphalt Association
North Carolina's contractors and agencies have engineered a pavement preservation tool for higher-volume roadways. Learn tools for cost-benefit analysis for thin-lift asphalts, how to determine whether this technology is the right approach for a given road, tips for preparing the production and construction crews to ensure success and how North Carolina built on data from other states.
3:00 PM - 3:30 PM
Roundtable Discussions
Participants will spend 30 minutes discussing the presentations in a roundtable format and prepare questions for the panel discussion.
3:30 PM - 4:00 PM
4:00 PM - 5:00 PM
Questions/Answers - Panel Discussion
The presenters are brought back to form a panel and answer the participants' questions which are presented by the moderator.
Tuesday, March 13
7:30 AM - 9:30 AM
Session III: Keeping Competitive
Session Moderator: Mike Kvach, Executive Director, Asphalt Pavement Alliance
MEPDG: The Importance of Calibration Validation
Kevin D. Hall, Ph.D., P.E., University of Arkansas
Kevin Hall will present an overview of the Mechanistic Empirical Pavement Design Guide and discuss how important it is to validate its calibration to local materials.
Overcoming Barriers to Asphalt Recycling
Audrey Copeland, Ph.D., P.E., Vice President, Engineering, Research & Technology, National Asphalt Pavement Association
When a group of asphalt pavement experts formed the RAP Expert Task Group in 2007, they identified the top 10 barriers to and needs for increasing RAP use among State DOTs. Five years later, every State now allows the use of RAP in asphalt pavements. However, high RAP use (defined as more than 25 percent by weight of mix) is still a challenge in some areas of the U.S. Participants will learn how DOTs and industry overcame these barriers and the resources that are available for using high RAP.
NCAT Research Validates High-RAP Mix Performance
Buzz Powell, Ph.D., P.E., Assistant Director, National Center for Asphalt Technology
Placement of high-RAP content surface mixes on perpetual pavements at the NCAT Pavement Test Track in 2006 have survived 20 million ESALs, proving the potential for long term performance in mill/inlay applications. Thinner structural sections were built in 2009 using high-RAP mixes for all layers to prove the potential for good field performance and improve laboratory characterization for durability and fatigue. Dr. Powell will explain the results of these tests and discuss how a modified laboratory fatigue testing program showed that high RAP mixes can perform better than virgin mixes.
Innovative Rehabilitation: Existing HMA Pavements
John Bellizzi, P.E., Retired Public Works Director for the City of Des Moines and Consultant to the Asphalt Paving Association of Iowa
Asphalt pavements which have been stage-constructed can be analyzed as existing perpetual pavements. Innovative, economical rehabilitation may include examination of deficiencies and subsequent thin milling and inlay with high density, high-RAP HMA.
9:30 AM - 10:00 AM
Roundtable Discussions
Participants will spend 30 minutes discussing the presentations in a roundtable format and prepare questions for the panel discussion.
10:00 AM - 10:30 AM
10:30 AM - 11:30 AM
Questions/Answers – Panel Discussion
